Its been up and running for ~2 weeks. It started showing the issue again ~3
hours ago. I have attached a graph showing read requests for the last week as
compared to another server. You can see that they were lower for this server
until ~3 days ago when they recovered on their own (we did not restart the node
but we did restart clients that day which likely caused the recovery).
I have also attached read/write request volume. Note we're using RF 3 for all
keyspaces.

> We are using the datastax driver and have seen the following exceptions

> start sending less write requests to the nodes where this occurs the most
